Transcutaneous Auricular Neurostimulation for TMD

This trial tests a new method called Transcutaneous Auricular Neurostimulation (tAN) to help individuals with Temporomandibular Disorders (TMD), which cause jaw pain and discomfort. The researchers aim to determine if daily, home-based tAN sessions, which send gentle electrical pulses to the ear, can reduce pain and improve mood and cognition. Participants will receive either real stimulation or a placebo that feels similar but is inactive. This trial suits those who have experienced TMD pain for at least three months and are open to trying this non-invasive treatment at home. As an unphased trial, it offers a unique opportunity to explore a novel, non-invasive treatment option for TMD pain relief at home.

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team to get a clear answer.

Research has shown that transcutaneous auricular neurostimulation (tAN) is a safe and practical treatment for various pain conditions. This method sends gentle electrical pulses to the vagus nerve through the ear. It is non-invasive, requiring no surgery, and is usually well-tolerated. Participants in past studies reported only minor side effects, making it a promising option for those with chronic pain.

Most treatments for temporomandibular disorder (TMD) involve pain relief through medications like NSAIDs, muscle relaxants, or corticosteroids, and sometimes physical therapy or surgery. But transcutaneous auricular neurostimulation (tAN) offers something different. It uses a non-invasive device that delivers gentle electrical stimulation to the ear, potentially reducing pain and improving function without the need for drugs. Researchers are excited about tAN because it taps into the body's natural pathways to modulate pain, offering a new, drug-free approach that patients can manage at home. This could mean fewer side effects and a more convenient treatment option for those suffering from TMD.

Research suggests that transcutaneous auricular neurostimulation (tAN) might help with conditions like temporomandibular disorders (TMD), which affect the jaw. Although direct proof of tAN's effectiveness for TMD is not yet available, similar methods have shown promise in easing pain and improving symptoms in related conditions. For example, other types of nerve stimulation have successfully reduced face and jaw pain and muscle soreness. In this trial, participants will join either an active tAN group or a sham stimulation group. tAN sends gentle electrical pulses to the vagus nerve, which can help manage pain and boost mood. This non-invasive method, which does not involve surgery or needles, offers an appealing alternative to traditional treatments.²³⁵⁶⁷
